Scope

Main technical content: This document specifies the terms and definitions, principles, general provisions, reagents, instruments and equipment, sampling, determination steps, precision, and reporting for the determination of chemical oxygen demand (COD) in high-chlorine wastewater from silicone. This document is applicable to the monitoring of silicone wastewater with a chloride ion content greater than 1000 mg/L (after dilution). For undiluted water samples, a 0.2500 mol/L potassium dichromate solution can be used to determine COD values of 50-700 mg/L, and a 0.0250 mol/L potassium dichromate solution can be used to determine COD values of 5-50 mg/L.
